This guide is written mainly for players new to playing retribution in arena and PvP.

Talents

In the talent picture I selected talents that I use as default in arena. Talents should be changed every arena match depending on what composition you're playing, what you're up against, and what strategy you and your opponent might execute. Read below for a more detailed explanation on talent choices.

Level 15:
Highly Recommended: Final Verdict

This increases your Final Verdict damage by 20%. Currently the other 2 talents just don't beat out the damage you can gain from Final Verdict in a PvP scenario.

Level 30
Recommended: Zeal

Crusader strike is rarely used on CD in PvP, this makes Fires of Justice a bit more lackluster.

Rarely do Rets run out of globals for things to do in PvP, making the longer CD on Zeal not much of a problem allowing it to buff our Crusader Strike damage significantly without a big cost. Due to this, Zeal will almost always do more damage than the other talents on this tier other than extremely specific situations.

Greater Judgment is useful in fast games but keep in mind Crits have reduced effect in PvP. Over a long-game unless the other team was above 50% HP the entire game and you were getting kited a lot Zeal will be superior.

Level 45
Recommended: Fist of Justice

Logic here for Fist is very similar to WoD, the other 2 talents are mostly used if you want to strategize around them. Repentance is somewhat improved in the fact that it doesn't use the CD if you cast it on a Beast, but you'll require a lot of effort to land it especially on Druids. Blind is essentially the same as before, not very useful unless you want to rush a game.

Level 60
Recommended: Blade of Wrath or Divine Hammer

Blade of Wrath provides the best consistent damage and also good holy power generation. Crits are also 150% in PvP, making Virtue's Blade much worse than it would be in PvE.

Divine Hammer is used if you play in a composition where AOE damage is useful. It should be used against any teams that you believe will generally be stacked such as melee cleaves. As long as Divine Hammer can occasionally hit 2+ targets it will beat out Blade of Wrath in terms of overall damage.

Level 75
Recommended: Any

Justicar's Vengeance has a lot of synergy with Divine Purpose. Basically, you use it with the proc or when the target is stunned. This talent is excellent especially in 2v2, when you hit healers a lot during stuns.

Eye for an Eye should be picked against any kind of physical damage team that will focus you.

Word of Glory is an okay choice against DOT cleaves that has a no physical damage component to it. Generally used when the other 2 is useless due to taking Crusade and no physical damage taken.

Level 90
Recommended: Divine Intervention and Divine Steed

Divine Intervention is an increase to our survivability. Not having to press Bubble when we get low is like a large indirect increase to our health-pool pre-bubble. This is generally my default talent.

However, our Mobility is horrible, and having at least one talent to help it is nice. If you plan to for example, chase a Mistweaver Monk in 2v2 you should use the mobility talents instead.

Level 100
Recommended: Divine Purpose or Crusade

Holy Wrath now does 35% of your missing HP as damage. This is still decent burst, but with the long CD mixed in Divine Purpose will almost always be superior outside of 2v2 Skirmishes or Duels. Crusade requires a ramp up time but is our highest damage burst talent in this tier. If you don't expect to get CC'd too much during your wings choose Crusade.

PvP Talents

Similar to the earlier talent picture this shows talents I would default to in arena, but PvP is a situational game and talents are constantly switched. Read below for a more detailed explanation on PvP talents.

Tier 1
Largely preference and situational based, Gladiator's Medallion gives you the most control of when you want to be out of a CC.

Adaption is nice for teams that has 5second+ CCs that your healer cannot dispel, adaption also has nice synergy with our artifact trinket. It is however a highly abusable talent by your opponents, make sure they're not a team that can cross CC your adapt to CC your healer easily.

Relentless is best for teams that constantly CC you over and over, I tend to use it against Sub Rogues if I don't need Gladiator's Medallion to trinket and get my healer out of a CC.

Tier 3Jurisdiction is the general default talent in arena. It's very difficult to use a 10yd range spell on healers you are not killing for CC.

Law and Order provides us with a much needed extra slow, this is the default talent in 1v1 or for open world fighting.

Tier 4Luminescence is an amazing talent, 20 yards is a huge radius for heals to be "cleaved". Holy Ritual is useful in double dps 2v2 or for solo play.

Tier 5Blessing of Sanctuary is what makes Rets unique in arena in my opinion. Being able to get your partners out of CCs this often is definitely one of our strengths. When you do battlegrounds or just feel like you want to do more damage Vengeance Aura is preferred over Seraphim's Blessing.

Tier 6Lawbringer is the highest DPS as long as you need to swap targets at all. This is what you'll be using the majority of the time.Divine Punisher is generally bad.Hammer of Reckoning has good synergy with Crusade especially against teams you need extra burst for. It adds 12 seconds to your wings when used with Crusade, allowing us to have 40seconds of Wings or even using "fake" wings to cause your opponents to pop CDs needlessly.

Viable Ret Comps

Legion allows much more diversity in general, you can be successful with many different comps. These are the best comps I have played this patch:

Ret | Hunter | Healer

Ret | Feral | Healer

Ret | Warlock | Healer

What rotation do you use in PvP?
There is no "specific" rotation in PvP.

If you're speccing Justicar's Vengeance keep in mind that JV does less damage in PvP than it would usually do. This is due to the spell templates in PvP, JV is nerfed in arenas and such meaning it does less than TV if the target is not stunned.

When to use Divine Storm?

If you're hitting at least 2 targets and you have the artifact traits Divine Storm will deal more overall damage and also provide a slight heal to your team. As long as it doesn't break CCs and your team can make use of the AoE damage, you will generally want to Divine Storm over Templar's when hitting 2+ targets. Divine Storm is also ranged so you can use it when getting kited.

You use JV when:
Target is Stunned
You have a Proc and you're missing a bit of HP
You really need the heal and you can't cast

You use TV when: (more damage than JV unless target is stunned)
Target is not stunned
You have a proc and you're not missing HP

What macros does Ret have for PvP?
Macros are largely preference. I use a lot of focus and party target macros. The goal is to be able to use your spells without changing your target.
Add #showtooltip to the start of these macros if you want to see it.
Some other general macros:
1.) Focus HOJ
/cast [target=focus] Hammer of Justice

2.) Focus Repent
/cast [target=focus] Repentance

3.) Focus Rebuke
/cast [target=focus] Rebuke

4.) Focus Judgment
/cast [target=focus] Judgment

The Support Macros I Personally Use:
(switch x with number or partyx with Toon Name)

General Arena Tips
Ret is a hybrid melee, with a large role to supporting your teammates. We have good burst damage during wings, but outside of that we're a bit gimped. We have some off heals and good support, but we're also incredibly easy to CC as a melee class.
As a ret pally, you always have to remember you ARE NOT a warrior. You need to watch your partners the entire game. Do not waste your off heals, and blessings. In an arena match my eyes are on my party screen the most.

Blessings are stackable now, you can use Freedom and Protection on the same target without it overwriting each other.

Good guide. Ret is a very gear dependent spec IMO, the "how much gear do I need to arena" should be removed. Instead, I would talk about best options for a Pvp dps trinket for those who are and are not raiders.

So glad someone made a ret guide instead of another holy one.

I don't think you should advise that we should forge into pure Mastery come patch 4.0.6 until more testing is done.

The new Mastery is still being worked on within the PTR and nothing is final. As of today's new build Redcape's current numbers still show Mastery as our worst stat, just barely coming behind Crit/Haste (which is better than before).

I believe that we should still try and balance out our secondary stats--which are of course, Crit/Mastery for PvP--if these changes go live then we wont change a thing on how we reforge.

lets say u crit a mage for 20k with Templar's Verdict with 8 Mastery, dont you think 36.8% dmg increase on it is bad? I mean it's AWESOME for burst, idk about substained dmg for pve tho but who cares about pve? I'm also pretty sure Inquisition makes it scale even better (and it's undispellable in 4.0.6)

8 mastery on a 20k TV = 27360... that's with base mastery and 20k on a mage isnt rare.

the burst it will be able to put out with undispellable Inquisition and undispellable Zealotry is going to be rediculous with a huge amount of mastery

I don't know where you got the idea that burst is more damage in an arena game than net DPS. Is it a comp issue? Can you not stick on your target? Whatever it is, the illusion of bigger numbers transferring into "better" is false in an Arena environment and PvE enviroment.

Log into the PTR for yourself and test it out; it may just be another preference issue. However, I've reforged into all Mastery and have balanced out both secondary stats (Crit/Mastery) and balancing out my stats has shown to be of greater value.
